Rosario Dawson

James Franco hit the red carpet at the Cannes Film Festival last night with his ex-girlfriend and current costar Ahna O'Reilly to premiere their new project, As I Lay Dying. The two were joined by costar Tim Blake Nelson as well as Rosario Dawson, who doesn't star in the film but does share a connection with James as they have both worked with Harmony Korine. (James starred in Harmony's most recent film, Spring Breakers, while Rosario made her film debut in 1995's Kids, which Harmony cowrote.) The premiere was a big deal for James, who also directed the movie. We caught up with Ahna earlier this week in Cannes, where she talked about how excited she was that James asked her to take on the female lead after the two had broken up. She said, "I knew James could get any number of actresses to play that role," adding, "I think he did a tremendous job and I'm so proud of it and proud of him."

Ahna also premiered her new project, Fruitvale Station, at Cannes earlier this week — be sure to check out Ahna, James, and all the other celebrities at the Cannes Film Festival!

January Jones stepped out for Coach's third annual Evening of Cocktails and Shopping at Bad Robot's headquarters in Santa Monica last night. She made her way through the star-studded party mingling with Chloë Sevigny and Milla Jovovich, as well as a Thakoon-clad Katy Perry, Conan O'Brien, Orlando Bloom and more. Orlando was without his wife, Miranda Kerr, for the charitable night out after she made headlines yesterday for speculation surrounding her contract as a Victoria's Secret Angel. He also stepped out without Miranda for a lunch date with friends earlier in the day.

The annual bash, which benefits the Children's Defense Fund, also brought out stars like Joe Manganiello, who had his girlfriend, model Bridget Peters, with him for the evening out. Other attendees included Kate Mara, who was accompanied by beau Max Minghella, Nikki Reed, and Rosario Dawson, who greeted fellow partygoer Amy Smart with a big hug, and also found time to catch up with Ellen Pompeo.

Rosario Dawson met up with ex-boyfriend Danny Boyle to premiere their new film, Trance, in NYC last night. She was joined by her costar Vincent Cassel as she joked around on the red carpet while wearing a stunning Bottega Veneta pink dress. Later, Rosario, Danny, and Vincent headed to the premiere's afterparty where the actress celebrated the arrival of a pizza delivery by cheering for joy. The cast weren't the only stars who attended the event, with The Walking Dead's Norman Reedus arriving on the arm of Debbie Harry, and Girls stars Jemima Kirke and Zosia Mamet catching a screening of the new flick.

The premiere comes hot on the heels of the announcement that Rosario and Danny had broken up, although it isn't clear how long the couple had been dating. The two were last seen together when Rosario donned a bikini during a vacation in Barbados back in January. There are rumors that Rosario is moving on with Michael Fassbender after the two were spotted together in London over the weekend.

Instead of wearing their hair in safe, chic chignons or down and sleek like you would presume in Paris, stars from around the world like Katy Perry, Rosario Dawson, Natalia Vodianova, Peng Lin and Amber Le Bon all decided to dare to be different. Take a peek at their hairstyles from the front row at Dior, Yves Saint Laurent and Jean Paul Gaultier, and let me know whose look you like best.

Johnny Depp made a special appearance at London's Royal Opera House last night to honor his friend Keith Richards. Keith was being feted by GQ at its Men of the Year Awards with the Writer of the Year statue, thanks to the runaway success of his memoir Life. Johnny took the stage to salute his good friend, but first said he'd been hidden to keep his cameo a surprise. Johnny commented, "They kept me downstairs in the basement — they locked me up!" Keith made a speech, revealing Life's being made into a movie. Bradley Cooper, who wore Tom Ford to collect his International Man honors, cozied up to Charlize Theron. Rosario Dawson wore a long dress from Tommy Hilfiger to speak, while Emma Watson, in McQ, paid homage to her Lancôme collaborator Mario Testino. Photographer Mario received accolades as the Inspirer of the Year.

Summer is just a few weeks away, and that means you're likely looking for some easy, hairstyles that keep your hair away from your face. Enter the ponytail. The great thing about this classic look is that you can wear it anywhere from sleek and shiny or tousled with a matte texture. See five ways to do it now.

The Cannes Film Festival may have wrapped up, but the remarkable style will live on forever. This year, the red carpets were walked by superstars like Penelope Cruz, Sarah Jessica Parker, Karolina Kurkova, and Gwen Stefani — and even brought out celebs Jane Fonda, Goldie Hawn, and Angelina Jolie. We enjoyed seeing all of the over-the-top, glamorous looks, but when forced to choose our faves, it came down to a very fierce 20 ensembles.

Gwen Stefani kept her Cannes Film Festival fashion coming this evening at the premiere of Sean Penn's This Must Be the Place, choosing a black-and-white gown with strategic cutouts. The singer went solo for the red-carpet debut after her husband, Gavin Rossdale, caught a flight out of nearby Nice this morning. Gavin and Gwen were together last night, though, for the amfAR Cinema Against AIDS fundraiser along with Kanye West, Bar Refaeli, and other stars. Sean was also by himself for today's unveiling of the film, without girlfriend Scarlett Johansson. Gwen's cycled through a collection of gorgeous gowns and dramatic outfits during her time on the French Riviera, but her trip hasn't been a completely formal affair — Gwen wore a bikini while enjoying the sun on a yacht with Gavin, Zuma, and Kingston this week.
